The URL that is passed as a parameter to the HttpClient delete() method has the ID of the employee to delete Delete button click event handler is in DisplayEmployeeComponent. So modify deleteEmployee() method in display-employee.component.ts file as shown below. deleteEmployee() { this._employeeService.deleteEmployee(this.employee.id).subscribe( () =] console.log(`Employee with ID = ${this.employee.id} Deleted`), (err) =] console.log(err) ); this.notifyDelete.emit(this.employee.id); } The success callback function logs the ID of the deleted employee to the console and the error callback function logs the error to the console.
